PREPARED ROOFING.

SPECIFICATION forming part of Letters Patent No. 753,982, dated March 8, 1904.

Application filed June 23, 1903. Serial No. 162,739. (No specimens.)

To all whom/it may concern:

Be it known that I, STANLEY R. HOLLAND,

a citizen of the United States, and a resident of St. Louis, State of Missouri, have invented' The object of this invention is to provide a prepared roofing constructed of various materials and coated on its outer surface with crushed shell.

In the drawings, Figure l is a perspective view of a roll of my improved prepared roofing, a corner thereof being separated to show the various layers. Fig. 2 is a detailed enlarged sectional View of a portion of the roofing material.

The prepared roofing consists, first, of a heavy layer -of felt 3, saturated with asphalt.

4 indicates a coating of genuine Trinidad asphalt, and 5 a layer of buckram or burlap saturated with asphalt.

6 indicates a coating of genuine Trinidad asphalt, and 7 represents crushed shell spread over the entire surface of the material and adheres thereto by means of the asphalt coating.

The one edge 8 of the material is provided with a margin, say, about two inches in width, which is sprinkled with a coating of marble.- dust 9. This is for the purpose of providing a perfect water-tight joint when the material is placed in proper position upon the roof and properly overlapped, bringing the end or felt surface over the margin.

The material is constructed in long sheets and when finished rolled, as indicated in Fig. l.

The essential feature of my invention is the manner of coating the material with crushed shell, the purpose of which making a neater, more even, and white roof, the shell retaining its color, whereas a material such as gravel and sand loses its natural color by being eX- posed to the weather and giving a dirty appearance to the roof. By the use of the marble-dust margin a more perfect joint can be made.

What I claim isl. A material for prepared roofing composed of layers of felt, burlap and asphalt adhesively retained together, the outer surface being covered with crushed shell, a margin formed on the one edge of the material and sprinkled with marble-dust, substantially as specified.

2. A material for prepared roofing composed of a layer of felt, asphalt placed on thel layer of felt, a layer of burlap located on the asphalt, asphalt placed on the upper surface of the layer of burlap, crushed shell sprinkled on therasphalt and adhesively retained in a perfect fiat position upon the surface of the roofing material, amargin formed on the one edge of the material, said margin sprinkled with marble-dust, substantially as specified.

In testimony whereof I have signedmy name to this specification in presence of two subscribing witnesses.

STANLEY R. HOLLAND.
